ADLINK OSM-MTK520 – A MediaTek Genio 520-based OSM Size-L system-on-module

ADLINK OSM-MTK520 is a 45 x 45mm OSM Size-L system-on-module (SoM) powered by a MediaTek Genio 520 AIoT processor with a 10 TOPS NPU for Edge AI workloads.

It’s basically an upgrade to the company’s OSM-MTK510 OSM Size-L module with a Genio 510 hexa-core SoC (3.2 TOPS NPU), up to 32GB eMMC flash, and 8GB LPDDR4 with a Genio 520 octa-core SoC (10 TOPS NPU), up to 256GB or 512GB UFS 3.1 storage, and up to 16GB LPDDR5 memory. There are also some minor changes to I/Os with an extra USB OTG interface, DisplayPort instead of HDMI, an extra MIPI CSI camera interface, fewer I2C interfaces, and more GPIOs.

ADLINK provides a Yocto Linux BSP for the module (not yet updated for OSM-MTK520) and can support Android and/or Ubuntu upon request.

I could not find any development for the MediaTek Genio 520 OSM module per se, but the company now offers an I-Pi OSM 510 Development Kit, combining the earlier OSM-MTK510 module with the OSM-EB4 carrier board. The latter might be reused with the OSM-MTK520 as is, or with minor modifications.

While it’s the first OSM module based on Genio 520 SoC we’ve seen, the processor was previously spotted in AMobile SoM-SD520 SO-DIMM system-on-module and Radxa NIO 5A SBC.

Two SKUs are currently listed for the ADLINK module: the OSM-MTK520-4G-64G-CT and OSM-MTK520-4G-64G-ER. Both are OSM Size-L modules with an octa-core Genio 520 SoC, 4 GB LPDDR5, and 64 GB UFS, but the former is standard, and the latter is rugged. More details. including a datasheet and a user manual, can be found on the product page.
